The invention relates to a method for operating an electric vehicle and to an electric vehicle. The electric vehicle comprises: an electric travel drive for a travel movement of the vehicle; a control device for controlling the traveling motion of the vehicle; a first energy storage device for supplying a first DC voltage to the control device; a second energy storage device for supplying a second DC voltage to the travel drive device, the second DC voltage being in particular greater than the first DC voltage; and an energy supply unit, which supplies a DC output voltage, in particular intermittently; wherein the first energy storage device is connected to the energy supply unit via a conversion device, and wherein the second energy storage device is connected to the energy supply unit, and wherein the conversion device converts the DC output voltage into a first DC voltage, in particular wherein the first DC voltage is smaller than the DC output voltage, a first power flow from the first energy storage device to the second energy storage device is blocked, and a second power flow from the second energy storage device to the first energy storage device is blocked.
本发明涉及一种用于运行电动车辆的方法和一种电动车辆,电动车辆具有:用于车辆的行驶运动的电气的行驶驱动装置;用于控制车辆的行驶运动的控制装置;用于向控制装置供应第一直流电压的第一储能装置;用于向行驶驱动装置供应第二直流电压第二储能装置,第二直流电压尤其大于第一直流电压;和供能单元,供能单元尤其是间歇性地提供直流输出电压;其中,第一储能装置经由转换设备与供能单元连接,其中,第二储能装置与供能单元连接,其中,转换设备将直流输出电压转换成第一直流电压,尤其是其中,第一直流电压小于直流输出电压,其中,阻止从第一储能装置向第二储能装置的第一功率流,并且阻止从第二储能装置向第一储能装置的第二功率流。
